[HTC Inspire 4G] jhester1967:
Ive been using the tasks widget from HTC and got a notification that there was an update for it through the htc hub. When I went to the hub to update it, it would not download and install the update correctly. It would say its installing when it was at only 56%?? Or sometimes even less then that and then the download would just disappear. So I thought maybe i should uninstall and reinstall the widget. Once I did it has never been able to fully download and install again. What should I do? And ive tried other task widgets on the android market and nothing else really looks as good or is over complicated for something so simple.
[HTC Inspire 4G] fernandezhjr:
HTC Sense is crap. It tells me updates are available for widgets, yet won't let me update them. It also won't let me download any new ones. My Friends stream no longer auto updates. It has never properly synced my contacts. There is usually one or two missing or a pic is wrong for one or two.

[General Topics] FloatingFatMan:
It's NOT a screen protector. It's not something you can just place over your screen and carry on. This is something that the manufacturers build in to the screen so is only of use to new devices utilising the technology.

Great idea, fantastic idea, for new phones only.

[General Topics] lude219:
It's about time. We're surrounded by an abundance source of photons (light) and it's great that we have the technology to harness that now.
[General Topics] egzthunder1:
The only issue I would see with this is that battery life (not the charge but how long it will last before you need to get a new one) would be drastically reduced as this would be a constant charging/uncharging of the battery, which will degrade it faster. Same concept as to why you should use your laptop unplugged.

Neat idea though.
[General Topics] lude219:
I see your point, but the reason why it's bad for the laptop is that the rate at which it's charging & discharging is almost instantaneous, not to mention, in large quantity. The cells are constantly being fluctuated.

This technology isn't going to replace wall charger anytime soon and it takes 6hr just to completely charge out in the sunlight (compare to ~2hr through wall charger), so it's not going to deteriorate the life expectancy of the battery at all, if any. Besides most modern batteries can handle a couple thousand charges until the performance diminishes, so chances are you're more likely to have gone onto a new phone before the battery takes a toll.

At most, this technology will help with standby time (10-20% in a day?), it's not going to fully recharge a phone under intense use.

[General Topics] Jaxbot:
It's nice technology, but I wouldn't give my hopes up to seeing this in products any time soon. Even if they do manage to launch the product by Q1 2012, which would be awesome, manufacturers will undoubtedly be slow to adopt this, and the testing process would probably complicate things, too.

Not to say I don't think it's a great idea, because I think it's awesome, but I'm not giving my hopes up :\

And hey, who remembers these from CES 2010?

[General Topics] wiggey1337:
craazzzy! i know simlar concepts have been thought of before but that really is something to be put into practice! looking forward to it being here in the next few years mainstreamed!
[General Topics] ionbasa:
It would be a interesting concept if it could also create current from the actual screen of the cellphone, because the screen is emitting light, you could practically charge your phone while using it, but don't expect unlimited power :P, theoretically you can have unlimited power, but practically photovoltaic panels are not that efficient yet.

I would also like to see this combined with using the radio wave energy to charge phones also, "wireless charging". There is so many radio waves that go to waste! especially when all that energy can be used to power/charge our devices!
[General Topics] Zalastax:
If this is that cheap as he said and it works you could use this at more places like between the glass of windows on houses and cars. Wouldn't it be possible to turn this inside out and get charge when the screen is on? Unless that dims the light it would extend the life a bit more.
[General Topics] mrsato:
Are you kiddin' me? ONE DOLLAR? First of all, it that turns out to be true, I'm absolutely buying it. Second, honestly, they're selling themselves short - its worth more. Hell, I'd pay a dollar for reach multiple of time I can go without charging. He was talking about infinite (as long as there was light), but if I could go twice as long, $2 would be a steal. If could go 3x as long, I'd feel guilty only paying $3. Consider millions of people would buy this, it doesn't make sense they'd jip themselves out of millions of dollars. So I think they'll wise up in the coming year before launch. But maybe they know there's a catch. Maybe the lifespan of this film is pretty short.
[General Topics] oka1:
Some basic business 1 dollar cost @ the factory typically is a 3-5 times cost at retail. Sill cheap, but the more interesting thing is the ability yo create a transparent solar collector
[General Topics] mattfmartin:
In all seriousness, how often is your phone sitting outside, baking in the sun? Mine, never
[General Topics] lude219:
Pretty sure it's just a reference point as to the charging capability of this technology at its most extreme example. What it means is that it's not going to magically replace your cellphone's battery, but merely extending the battery when it sits hours on standby.
[General Topics] stylus1828:
Great technology. Maybe in the near future this technology will be used on electric cars and maybe in our houses. Use the thin foils on the windows of the car and houses.

I think this is a great idea in concept, but not in use. I don't think our phones would last very long with our sensitive touch screens in direct sunlight all the time... Can't wait to see what this evolves into over time though.
[General Topics] hellcat82:
Yeah direct constant sun exposure would probably make short work of the display panel. However, charging in indoor lighting, while not as effective, would probably be the most useful application. Every time the phone is out of the pocket it's pretty much guaranteed to trickle charge.

I'd kill for it on the Desire HD.
[General Topics] FC1032:
I get that it runs by sunlight and indoor light (though less effective), but would it be possible to simply make it collect energy from the screen's backlight (emitted) light as well?

Even better collect light from the sun/indoor light AND the light from the phone? Hahaha, just some wishful thinking :)
[General Topics] BluDiablo:
U guys think that's impressive they have nuclear powered batteries on the way :O and they are claiming they can make the battery as small as the width of hair! Right now the technology is a bit bulky...its the size of a freakin' penny! Here's the link guys.

[General Topics] ephestione:
Yup, phone integration in future models is the only way to go, especially since the guy said the films only costs the equivalent of one dollar for a typical phone (which leaves me quite surprised/unbelieving).

I just wonder about the battery life with so many and frequent charges. Anyone knows what happens when you always use your laptop plugged to mains and with the battery still inside.
[General Topics] DeathJester:
This is useless and will never catch on.

[General Topics] DeathJester:
There's no issue with frequent, small charges. Ni-Cd rechargeable batteries used to suffer from a memory effect, where the point where they were previously charged from became the new "0%". That doesn't happen with Ni-MH. They in fact fair better when recharged frequently, as allowing a Ni-MH battery to discharge totally can cause polarity reversal.
[General Topics] dexx0008:
be nice as supplemental power if indoor lighting can give you just a bit more juice that could be very welcome at the end of day. love technology.
[General Topics] cheskote:
be careful with this: exposing your device to direct sunlight will heat it and probably will reduce your battery life.

Heat is one of the worst enemies of lithium batteries.

well, the actual solar chargers take about 5 hours to charge 10% of the battery, so i hope this work much better than that

[General Questions and Answers] whenufeel:
remove some ".so" files after apk is intalled or while apk is being installed?

I am now creating an application which needs many "so" libraries that

is necessary to provide optimal process for each arm processor, e.g.

ARM9, ARM11, CORTEX.

The thing is I would like to remove useless "so" libraries after the

processor of a smart phone is known,

For example, if my smartphone runs on top of ARM9, I would like to get

rid of "so" libraries for ARM11 and CORTEX.

Would you guide me how I can handle this problem?

I'm waiting for your answer.

Thank you for your reading.
[Nook Color General] doncaruana:
I've seen modifying build.prop, using sqllite, and changing the name of the otacerts file. Doesn't seem build.prop is valid here until someone gets a hold of one with the new update. But I don't want to lose my root. So, what's the consensus? (please vote in the poll)

Here are the 3 mentioned:

1. Rename OTA Certs

2. Use Sqllite

3. Edit Build Prop

The build.prop is sort of experimental but seems to be working so far from reports.
[Nook Color General] ADude:
The consensus is definitely to read the other 1000 threads on the subject before starting yet another one.
[Nook Color General] doncaruana:
Really? There are 1000 other threads that compare all 3 options?

All the ones I read are where someone brings up one thing and then a few other people chime in on a different one. I was trying to find out, in one place, what the most recommended one was.

It is my fault for not creating a poll at first.

It is your fault for being a jackass.
[Nook Color General] dsf3g:
I'd say he's read the 1000 threads, given the fact that he rattle off a list of suggested solutions from those threads.

FWIW, I too am interested in knowing if this issue has been settled. Just rooted my NC the other night, am really enjoying all teh apps I've downloaded and would be happy to block updates and wait for a rooted 2.2 update.

So if anyone knows the definitive answer ot the OP's question, please do let us know.
[Nook Color General] Mark_OB1:
for what it's worth

Don,

I haven't read the reputed 1,000 other posts on this topic, so I don't know what consensus may have been reached there, but this is my take on it:

- otacerts renaming isn't going to be reliable

- the sqllite fix (modding the fota.mode item) is a permanent fix, which eliminates any possibility of OTA updates creating problems

- modding build.props may work, even if you don't have a master to reference from.

I.e., some reasonable higher settings for ro.build.version.incremental, ro.build.description, and ro.build.date MAY do the trick, even if they're not a clone from a legit updated version. I don't know (perhaps someone else does) if perhaps only one of those is really necessary, E.g., something like ro.build.description=2.1.0.428.int.enc.rrdp.s39975 may be enough to do the trick, since it holds the main versioning string (currently at 1.1.0.328).

So my recommendation if you want to be sure would be to do the sqllite fix.

- Mark

Flash CM7..... problem solved ;)
[Nook Color General] doncaruana:
I added links to the 3 methods I mentioned, for everyone's reference anyway. I did also read somewhere that someone said that installing CMR would stop OTA updates as well. But didn't see a lot of discussion about that.
[Nook Color General] migrax:
I don't think CM7 is ready for prime time on the NC. Last I saw video driver and flash still had issues. I too would like to see a 2.2 stock update so it could be rooted. BTW I am running Nookie Froyo right now and it is pretty sweet.

I tried the CM7 Agnostic SDCard option and nightly build and, well... did I mention it isn't ready for prime time?

But I am one of those fringe lunatics that never says anything important, never gets noticed, and is instantly marginalized. I'll likely die an early death and no one will notice...

Sorry, to get back on topic, I don't think CM7 is ready yet for Nook Color.

Nothing to see here, move along.

[Nook Color General] colorado_al:
Agree. CM7 is not quite up to where it needs to be as a daily driver.
[Nook Color General] khaytsus:
build.prop flat out works... End of story.

Of course someone needs to get the build.prop from the new one when it's released, so if you're really scared about it, stay off wifi I suppose. But it usually takes a while before people start getting it.
[Nook Color General] A. Nonymous:
The build prop only blocks one update. In order to block the Froyo update, you'd need the build prop for the Froyo update. That would only work until there is another update. Then you need the build prop from that update to block it. It becomes a vicious, never ending cycle. I may be incorrect in my understanding though.
[Nook Color General] Pre-dawn raid:
I don't think anyone really knows at this point which is why there are "1000 threads" on the topic. We just all have to sit back, drink a beer or 7, and wait until the next update is being pushed out. I personally went with the SQlite edit in Root Explorer. Seemed like the easiest way to me.

Update questions

I'm running Android 2.1 on my rooted Nook Color. What will happen if I don't block Barnes & Noble's upcoming update in April? Will my NC merely become unrooted and operate like a regular stock Nook Color? Is it possible that any damage will be done to the NC?

I'm actually curious to see exactly what an updated, unrooted NC will look like and how it will operate. I know that somebody eventually will come up with a way to root an Android 2.2 Nook.
[Nook Color General] rickrich:
My rooted 1.0.0 NC (Dec. ~8 autoroot) ignores the updates *DOING NOTHING AT ALL*. I can use the Market, download books from BN, etc.

Knock on wood!
[Nook Color General] sabinblitz:
From what I've read on other Andriod devices, it relocks the device and you lose superuser. Still, I'm curious if all the apps I downloaded with root will work after the update. The device was a b-day gift for my sister and she really loves the e-reader aspect, hence why HC and nookie froyo haven't been slapped on there.
[Nook Color General] MoCoTerp:
Well, if you run the stock launcher on a rooted Nook, you still see all the apps you have downloaded from Market in Extras. So I would assume that the 2.2 upgrade could preserve the apps you have on there. Though, I would always recommend doing a backup, getting updated, wait for whatever exploit is employed and re-enable your apps.
[Nook Color General] Divine_Madcat:
Don't tell that the to hundreds of CM7 users running this as a daily. ;)

Honestly, the only functionality "hurting" right now is video performance, as caused by an audio wierdity. Past that, I can't think of alot of broken stuff CM7 needs fixed. Sleep battery performance can be improved i guess... as it is, i like CM7 ALOT more than Froyo (no more SOD!)
[Nook Color General] HarleyChick:
I'm with you. Tried the CM7 from SDCard yesterday. It was okay, but it didn't exactly rock my world. Waiting for all the bugs to get worked out. In the meantime, sticking with Nookie Froyo. :)
[Nook Color General] xwint3rxmut3x:
I skipped over Nookie Froyo, but I used stock Root for awhile, and i've been on Cm7 for awhile and I love it. I agree video is not at 100% on cm7, but I really don't spend alot of time watching video on my nc at all. I downloaded the nook app from the market, and the tablet works great. The devs have done a great job, I have no issues using CM7 as my daily driver.

Gotta back you up madcat since we're the only pro CM7 users on this thread :D
[Nook Color General] polarborn:
CM7 and video

I also like the rooted Froyo - great for trips and business meetings. I do use the video player alot for recorded MP4 movies. Probably not the right forum but, can someone point me to a thread or video of how well CM7 runs MP4 videos?

Thanks in advance.
[Nook Color General] lschroeder:
Not good yet. I ask questions about mp4 over here using phiremod's CM7 ROM

http://www.androidtablets.net/forum...v5-1-oc-kernel-cm7-v21-base-22.html#post67993

Running a Froyo, Gingerbread, or HoneyComb emmc ROM blocks updates. Is that correct?
[Nook Color General] zenaxe:
FWIW, I'd fully expect/plan for it to wipe data & cache on the device. My 1.1 rooted nook wiped data just last weekend because I logged in a second google account and then tried access the B&N library app.

Use Titanium backup and Clockworkmod recovery to backup your stuff. IMHO. There's really not much excuse for not doing it.
[Nook Color General] combustiblemonkey:

[Nook Color General] fpga_guy:
Any updates, status?

I read a note that sqlite fix didn't block the 1.2 update. Any comments?
[Nook Color General] xdajunkman:
I started a thread that asked a similar question. Not too many responses, but there was one user who had done the db sqlite business and received the update anyway. He seems to be the only one reporting this so far, but if his experience is repeated by others then it is safe to say that the only way you are safe from a forced OTA update is a custom ROM.

I will join the minority in supporting CM7. There are really no flash or video problems that I experience. There are some discussions with guys arguing about trying to get high-bitrate 720p videos running on the thing and having problems....but come on who really needs that on a 7-inch screen. I have converted several DVDs to MP4 files that play very well in any player, including *gasp* the stock video player. I have been on CM7 since before the first stable build was released and have had no problems.

In my mind, the only legitimate complaint is the lack of deep sleep and subsequent increased battery drain. This is not really a bug as the device never sleeps and so there is no 'sleep of death.' I still find that with moderate to heavy use I can go two days without charging, so I don't find it to be a major problem. Besides...it only takes like 45 seconds for the thing to boot, so if I am not going to be using it for a while I just shut it off.
[Nook Color General] 511pf:
CM7 is a great piece of software, but the battery life issue is the only reason I don't use it. Having poor battery life and waiting for a device to boot up defeats a major reason to have a tablet in the first place. My laptop has those problems, which is a big reason I bought a tablet. I'd definitely be willing to kick in some money to get this problem fixed.
[Nook Color General] fpga_guy:
Hope to focus this thread as the title states on blocking OTA and not the merits/demerits of CM7.

I am keeping two NC rooted with Auto-nooter 3.0.0 on wifi. I will update weekly if I don't get updated/upgraded to 1.2 automatically.

So far - no updates.
[Nook Color General] magicland:
I used sqlite to attempt to prevent updates on my rooted 1.1, so far, so good. I've gotten an email from B&N about downloading the update, but nothing has attempted to update itself yet.
[Nook Color General] dino-oakland:
I too did sqlite (changing of one database field to manual). I have trouble with ADB, so I used the Root Explorer method mentioned by "RootNewbie" as one of the comments in the Sqlite post. It cost me a few dollars to buy the two apps he mentions, but hopefully it will be worth it.
[Nook Color General] dsf3g:
I did the sqlite method also. However, I've also turned off WiFi while I wait and decide what to do. I have a long trip May 7, and want to use the NC for watching movies. May wait until after the trip to decide what to do.
[Nook Color General] Hextall:
Which OTA blocking methods did you use, if any?

I did the sqlite database tweak, but as the previous poster mentioned, I turned off wifi until I see some kind of info beyond the one poster in another thread who said it didn't work.

I'll probably turn on my wifi next week (i have a trip this weekend that I can't risk having the nook do weird things if the OTA update tries to install). I'll post what happened, if anything, later next week.
[Nook Color General] 511pf:
I did the "easy" SQLite database tweak and checked that it survived a reboot. I have wifi on, so I will report back if I my Nook is upgraded.
